Throughout the United States, there is
no single major metropolitan area more
closely connected to organized crime’s
rapid ascendancy on a national scale
than New York City.

In 1920, upon the advent of Prohibition,
Gotham’s shadowy underworld began
evolving from strictly regional and often
rag-tag street gangs into a sophisticated
worldwide syndicate that was — like the
chocolate egg creme — incubated within
the confines of its five boroughs.
